There is a reason that they make cheap shampoo for kids. It's because kids can not resist dumping out all the contents of the bottle to make a big ole' bubbly mess.
This is what I found when I went to see what was taking Monkey #3 so long in the shower.
First of all he was running the shower with the drain stopped to make it a shower bath. Second, he emptied not one but two bottles of shampoo into the tub.
ARE YOU FREAKING SERIOUS! Oh thank the Lord that it is bedtime for monkeys. I need a breather. I have tried pump bottles, small little shampoo bottles but that darn boy just can resist the bubbles.
